Improvement in cultivators



UNITED 'STATES JOHN w. INGIEAND II. WRIGHT, OF LIvINGs'rON, ILLINOIS.

IMPROVEMENT IN ouLTlvAToRsf Specification forming part of Lett-ers Patent No. 46,675, dated 'March 7,'1-865'.' I

To all whom it may concern.'

Be it known that we, JOlIN'W. INGLF. and

R. H. WRIGHT, of Livingston, in the lcounty of.

Moultrie and State of Illinois, have invented a new and Improved Gultivator.; and we do hereby declare that the followin'guis afnll,

clear, and exact description thereof, which will enable others skilled in the art to make and use the'l same, referencel being had to the,A

accompanying drawings, forming.;` part of this specification, in whichj v A r Figure 1 represents a side sectional view of our invention, taken' in the -line :v Fig.- 2;4

Fig. 2, a plan or top view of the saine.

- Similar letters of reference indicate like parts.

This invention relates to a new and improved'eultivator designed for cultivating those crops which are grown in hills or drills; and it consists 1n a novel construction of the parts, whereby the plows may be adjusted laterally when the machine is iiimotion or at work, in order that the plows maybe made to conform to the sinuosities of the-'ro ws ot' plants, and the plows also lreadily elevated 'out of the ground, the plows being' under the complete control ofthe operator.

A represents an axle, having a wheel, B,

l'tted loosely on. each end of it, and. adraftpole, C, attached'centrally to uit'.

-D represents a V-shaped frame, which is attached by a bolt, a, to the undersideof the axle A, and is` allowed to tur'n freelyon `said bolt.

E is al bar, which is slightly inclined from a horizontal line, and is .secured tothe axle A in the same line with the draft-pole C, said bar having the drivers seat F ou its outer end.

G Gr 'represent two levers, which are connectedv by joints a. a', one to each side of the draft-pole C.l The front ends of these levers are attached to the front part of the frame D, and said levers ecxtend' back to the driver-s seat F, and are curved or bent upward, so that they `may be readily operated by the feet or knees ot the driver, f

To each side of the frame 'D'.there are at; tached, by pivots b, two standards, H H. These standards have each a plow, I, of-'shovel or other. form, secured to them. The standards Hare-allowed to work or turn freely on their pivots b. L '.lhev front plows arerather nearer toget-her than 4the rear plows, and the standardjsH H have each a segment-bar,J,attached to them by a pivot, c, the upper ends of the bars J J having oblongcurve'd slots d madein thennr througnwhi'ch pins e pass into frame D.v

K K are segment bars, which are attached `to the front' standards `H'H bypivots f, and also have oblong curved slots g maiieinthem",

through whiehpins h pass'into thefrarne D.

These bars K extend upward aboveth'elframe D, andhave each" alever, L, connected withI them, -said levers-.haviugl their fulcrat" at the upper ends of uprights j, and extending back -within convenient reaching distanceofthe driver on seat F. The"v rear' 'standards H are' connectedto the forward .ones by rodsk.

From the above description it will be seen v l that as the machine is drawn along the plows maybe nioved or adjusted laterally to' confd'rm to the sinuosities'of the rowsof plants by actuating the levers G G, and the plows may be raised outset-the gron nd,when desired, by-actuating ,the levers L L, the segments K of the front standards being raised, and consequently the front standardsH, motion being commu- .nicated from the latter to the rear standards bytherodk. The segment-bars'J K serve as'` guides forthe plow-standards. j
